Silverfish (Zygoptera: Lepismatidae), like this specimen from the genus Heterolepisma, live in warm, humid environments, which is why they can be frequently found inside homes. They're harmless to humans, but can be pests in libraries, since they can feed on paper and binding glue.
A cotton stainer bug, Dysdercus mimuloides (family Pyrrhocoridae). This genus contains several important agricultural pest species; they leave yellowish stains on cotton when they feed.
A leafhopper in the family Derbidae. The hypertrophied cephalic structures are due to the presence of strong muscles that move the cibarium, a pump-like structure that allows them to extract liquids from plant stems.
